TOALL WHM IT MAY GONGERNz' Be it knowny that N. B..SHERWO0D, of Millvillc', `.in Vthe county of Orleans, and State of New York, havel ,invented certain new and useful Improvements in Cotton-Seed Plantersg and I do hereby declare that the following is a full, clear, and 'exact descriptionthereoi, reference being had to the accompanying drawings, making part of this specificatiop, in which- Figure 1 s vertical section o f my invention, taken in the plane of the red -line :z: invig. 2.

Figure 2 is a transverse. section of the seed-box B, taken in the plane of the red `line-n in--g. 1.

Like letters-indicate corresponding parts in both figures. I

This inventionrelates toimprovements upon the seeddistributers i'e .resented.in my two former patents of June 5, 1866; and its nature consists in substituting for the carrier-belt of cotton-seed planters one or more' flat-.link chzrinsrunning over suitable driving-pulleys,l and carrying the seedconveyers.

To'enable others tomak nnd'use my invention, I will describe its construction and operation.

` I use thesame seed-box, B, and follower-board, A, as shown and describ-edin niyformer patents, togetherwith the separating and delivery-brushes, not shown in this case. Instead of the carrier-belt then used, I attach each cluster of-teeth, D, which constitute the seed-conycyers, to a platea, havin-g ashank, show-n at t', igfl, which is'pivoted"between the two plates of' a. doublelink of thechain. One great objection toz'the former beltsv was' the` reat dicult ex erienced in reventinfr them from, sli in in which casethe `seed was not aid S Y vP P e PP g P outfwith any regularity; but `these chains are-found to entirely obviate thisV diiliculty. v

There may he several 'conveyers attached to each chain, and so arrangedthat thoseof the several chains,-

if morethan onelis used, shall follow eachother diagonally acrossjthe vertical surface, up which .the seed is carried for delivery. f

The`chains C are d rivn bythe V-shaped teeth 1 of the pulleys P, hung upon the driving-shaft S. The

slack of the chains is'taken'np' by.fillinlg the space below the pulleys with wood, Aif desired,1 and cutting grooves the track of the'teeth and the' side of the boxQB. "But one chain might be used these bands mighthe made wide -enough to coverthewholespace, except that in the track of the centre links of the chnins', which would onlyleave an opening forA the shanks of the teeth-plates a to pass through. This construction leaves no v recesses for the seed to vlodge in, Aand 'consequently them'achinewill not clog.-

There may b'e oneor more fingers attached to the sidefchnins, to act as stii'rers toloose'nwthe seedbetween D upon proper offsets, so as to sweep `the entire width of the seed-box.. Any flexible -hand'or a rope might be usedas carriers instead of -the chains, it' run in serrated grooves in vthe driving-pulley. The drivingshaft S maybe connected vto one `of the ground-'wheels of'the.machine by eann g B; connecting to one sideot the seed-boi:` B a narrow box'and one chain, with suitablecouv'eyers attached, the same machine -uiay be used as a. corn-planter.'

What I .claim as my invention, and desire to secure by 'Letters Patent, is- 44Il fflh'e construction and relative, arrangement, in connection with' the chains, of the conveyeiD,^suhstan tiallyin the m'aimer 'and for the purposes herein shown and described.

2., The application of the flat-link chains C, with conveyers D attachechto cotton-seed planters, substan tially in the mannerand for the purposes shownand described. v l

3. The 'sunken channels within-'the drums 'P, and Athe surface-board J, for the carrier-chains 0, or their equivalents, to travel in,'for the purposes herein shown and-described,
